5SU1656-1KK16 SIEMENS

The 5SU1656-1KK16 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from Siemens, designed to provide comprehensive protection against both short circuits and residual currents. This RCBO has a breaking capacity of 6 kA, making it suitable for residential and commercial applications where moderate fault currents are expected. It features a 1P+N configuration, meaning it protects one phase and the neutral conductor, ensuring complete circuit isolation in case of a fault. The device is a Type AC RCBO, which is sensitive to alternating current residual currents. With a residual current tripping sensitivity of 300 mA, it provides a balance between protection against electrical shock and nuisance tripping. The 5SU1656-1KK16 has a C-characteristic tripping curve, making it suitable for circuits with moderate inrush currents, such as lighting and general-purpose circuits. Its rated current (In) is 16 A, and it is designed for a rated voltage (Un) of 230 V AC. This RCBO combines the functions of a circuit breaker and a residual current device in a single compact unit, saving space in the distribution board and simplifying installation. It is designed to protect people and equipment from dangerous electrical faults.
